Construction Materials FAQs FAQs
What every Chennai homeowner should know about construction materials — quality, brands, delivery, and verification.
Which cement brand is best for house construction in Chennai?+
UltraTech, Ramco, and Dalmia are widely used and trusted brands. The right choice depends on your structural engineer's preference, local availability, and specific application. Always use ISI-marked cement and verify manufacturing date (use within 3 months).
What steel grade should I use for my house?+
Fe500D is the recommended grade for all structural reinforcement in residential construction. Always demand Mill Test Certificates for each delivery of steel to your site.
Is M-Sand as good as river sand?+
IS-compliant M-Sand with proper grading and silt control is suitable for concrete and masonry work. Quality M-Sand is widely accepted in Chennai. The key is using IS 383:2016 compliant M-Sand from a licensed processor.
Can I use sea sand for construction?+
Never. Sea sand contains chloride salts that corrode reinforcement steel over time, compromising structural durability. Sea sand is not permitted in any structural application.
What is a Mill Test Certificate (MTC) for steel?+
An MTC is issued by the steel manufacturer confirming the batch meets IS standard specifications for grade, ductility, and yield strength. Demand MTC for every steel delivery to your site.
What is the concrete grade difference between M20 and M25?+
M25 concrete has a characteristic compressive strength of 25 N/mm² at 28 days. M20 has 20 N/mm². For residential RCC structures, M25 is the minimum recommended grade for all structural elements.
What pipe material should I use for water supply in my house?+
CPVC pipes are the preferred choice for domestic water supply (both hot and cold). Avoid GI pipes which corrode internally over time. For drainage, uPVC and SWR pipes are standard.
Which brand of electrical wire is recommended?+
Havells, Finolex, Polycab, and Legrand are trusted brands in India. Always use BIS-marked FRLS wire. Do not use unbranded cables in concealed wiring — they cannot be easily replaced if they fail.
Does Buildogram supply materials?+
